SPECIFICATION forming part of Letters Iatent No. 695,170, dated March 1 1, 1902.

Application filed May 11, 1901. Serial No. 59,853. (No model.)

To all whom it may concern.-

Be it known that LCHARLEs J .QUINN,a citizen of the United States, residing at Scranton, in the county of Greene and State of Iowa, have invented a new and useful Chimney-Cap, of which the following is a specification.

This invention relates to chimney-caps, and more particularly to that class wherein the same are made adjustable to permit of their being properly fitted around the coping of the chimney.

The device of the present invention is designed to supersede the galvanized-iron hoods commonly employed for supporting the smoke-pipe, whether cowl-bearing or other. The objection to the galvanized-iron hoods referred to is that their term of life is limited, as they soon rust or rot away, thereby requiring frequent replacing. Aside from this their attachment to a chimney is not of a 'stable character, so that they soon become loosened under the strain imparted to them from the pipe, due to wind-shaking, and thus loosen the bricks and mortar, resulting in a detachment from the chimney of the hood.

Aside from the form of chimney-hood referred to there are others in common use; but all have inherent disadvantages, inasmuch as they dependfor securement in place largelyupon the holding capacity of the mortar.

It is the object of the present invention to present a chimney-cap which may be readily adjusted to achimney and when once positioned will be held securely in place thereon.

A further object is to combine with the cap a smoke-chamber of a shape to concentrate the smoke, thus to cause it to escape from the smoke-pipe to be associated with the chimney-cap.

A further objectis to provide a thoroughlyefficient means of attaching the smoke-pipe to the cap so that it will be rendered rigid and be shielded from damage, as by high winds.

A salient and important feature of the present invention that difierentiates it from the art is that when the smoke-pipe has become useless it may be readily replaced bya new one without disturbing the cap.

Another and salient feature of the invention is that the cap constitutes a covering for the top of the chimney and supplantsthe use of the blue-stone or other stone caps heretofore used, resulting in increase in the strength and durability of the chimneys and reducing to a minimum the danger of the mouth of the chimney becoming damaged from Wind and weather.

With these and other objects in view the invention consists, generally stated, in a plate of a size to cover the top of the chimney, the plate to be provided with means for clamp= ing it securely on the chimney-coping either interiorly or exteriorly thereof.

As a matter of further and specific improvement I combine with the plate a smokechamber provided with an opening to receive the smoke-pipe, the contour of the chamber to be such as to concentrate and direct the smoke toward the smoke-pipe.

As a matter of further and specific improvement I construct the plate and chamber of cast-iron in one piece, so that in use it will be practically indestructible and from its weight will prevent the upper row of bricks of the chimney from becoming loosened or falling from the separation or destruction of the mortar between their joints.

As a matter of further and specific improve ment I cause the means for holding the cap in place on the chimney to constitute braces for the four sides of the chimney, so that tendency to outward bulge or spreading of the mouth of the chimney, such as frequently occurs, will be entirely obviated.

The chimney-cap of this invention is compact in form, can be cheaply made and readily applied to position for use, and when once seated in place may constitute an integral part of the chimney.

The invention consists, furthermore, in the construction and combination of parts. of a chimney-cap, as will be hereinafter fully de-' scribed and claimed.

In the accompanying drawings, forming a part of this specification, and in which like numerals of reference indicate corresponding parts, I have illustrated a form of embodiment of my invention capable of carrying my ideas into effect, it being understoodthat the arrangement and construction of the parts may be departed from without changing the scope of my invention, and in these draw- 1ngs- Figure 1 is a View in perspective, exhibiting a chimney supplied with a chimney-cap embodying my invention, the smoke-pipe communicating therewith being indicated by dotted lines and also the guy-wires for holding the pipe in a vertical position. Fig. 2 is a view in top plan. Fig. 3 is a longitudinal vertical section. Fig. 4 is a perspective detail view of one of the cleats or clamps detached from the device. Fig. 5 is a detached detail View in plan, showing more particularly the arrangement of one of the cleat-carrying recesses.

Referring to the drawings,I have illustrated in Fig. 1 the application of my device to a chimney, this device comprising, essentially, a base-plate 1, a smoke-chamber 2, and cleats or clamps 3, associated with the plateand to operate to clamp the same securely in place upon the coping of the chimney. The plate 1 is to be made of a size approximating the area of a chimney-top; but in the event of its being larger or smaller than the top this defect can be remedied by the cleats or clamps 3, which are adjustably connected with the plate and are shown in this instance as bearing against the outer side of the coping of the chimney, it being understood that I do not limit my invention to having them so disposed, as they may be arranged to bear against the inner side of the coping of the chimney, to effect which it will only be necessary to reverse the position they occupy with relation to the plate, or, in other words, turn them end for end. As this will be readily understood, detailed illustration will be deemed unnecessary. The plate is provided on each of its four sides with a recess 4 to be engaged by the cleats or clamps 3, the cleats to be of the same thickness or a little thiner than the plate, so that when positioned within the recesses. they will not present interfere with the ready adjustment of the cleats. The recesses 4 are covered by a plate or offset 5, formed integral with the plate or, if preferred,secured thereto, the offset to pre sent a rigid bearing against which the upper side of the cleat will bear, the offset being provided with an orifice 6 to be engaged by a bolt 7, carrying at its upper end a nut 8, the bolt to pass through the cleat, so that upon tightening of the nut the cleat will be rigidly secured in place. In order to permit lateral adjustment of the cleat with relation to the plate, the bolt-opening 9 therein is an oblong slot of a length to permit such adjustment of the cleats as to allow the cap to be seated uponchimneys of considerably greater width than the plate. The advantage of this adjustable feature of the cleats will be readily apparent, as it will be seen that by this feature alone the necessity of making the plates of various sizes to suit different chimneys will be obviated-that is to say, should the chimney be two inches broader each way than the size of the plate this extreme width will be compensated for by the adjustable cleats.

In the center of the plate is an opening 10, preferably oblong or rectangular,and covering this openingis the smoke-chamber 2, the same being a hollow truncated pyramidal structure integral with the plate or secured thereto, as may be preferred, the upper face of the chamber being provided with an orifice 11 to be engaged by the smoke-pipe 12, (indicated by dotted lines in Fig. 1,) the smoke-pipe to be rendered rigid and held against vibration by guy-wires 13, secured to the pipe and to a suitable part of the chimney or to the plate. Where the guy-wires are secured to the plate, this may be provided at its four corners with perforated ears or eye'bolts 14, in which the ends of the guy-Wires will be secured. The smoke-chamber 2 proper, formed in part by the walls of the opening 10 and by the sides, ends, and top of the smoke-chamber, is, as stated, preferably pyramidal in contour, this shape being found advantageous and serving to concentrate the smoke and guide it toward the smoke-pipe, and, further, increasing the facility with which the structure may be cast,

as by the inclined faces presented by the outer and inner surfaces of the smoke-chamber,

the drawing of the pattern of the cap fromof the offsets 5, as these may be varied or i changed and still be within the scope of my invention, the salient and underlying feature of the invention in this connection being the presentation of a chimney-cap provided with means to permit of its rigid attachment to the chimneyand with a means of attachment to the smoke-pipe.

Each cleat 3, as herein shown, is approximately L-shaped in elevation, this being a simple and effective form of device for this purpose; but it is to be understood that its shape may be changed partly or wholly and still be within the scope of my invention, the

point being to provide an effective clamp or cleat for holding the chimney-cap in position upon the chimney.

The cap is here shown as applied to a square.

and not considered a principle of the structure per se, although necessary elements in effecting the assembling. From the fact that the device is composed of so few number of parts it will be apparent that it can be manufactured at a low cost, and by reason of its adjustable features it may be applied to a chimney with readiness and ease. From the fact that it is made of cast-iron, with all of the parts except the cleats, bolts, and nuts integral, it will present a rigid and stable structure, not only for supporting the smokepipe, but also for preserving the chimneymouth against disintegration.

In constructing the cap per se, as pointed out, the parts will by preference be cast integral; but it is to be understood that I do not limit myself to this particular mode of constructing the cap, as the same may be made in parts and assembled.

In applying the cap to a chimney the same is placed over the month, if preferred, on a bed of mortar, although this is not absolutely essential, and the cleats are moved in against the outer side of the coping of the chimney, after which the nuts 8 are tightly screwed down, thereby securing the cap in place. As before pointed out, instead of having the cleats bear against the outer side of the chimney-coping they may bear against the inner side, and to effect this it will be only necessary for the person setting the cap to insert his arm through the opening 11 in the top of the smoke-chamber, force the cleats against the inner side of the coping of the chimney, and then tighten up the nuts, as before.

I have found by actual use that by providing the plate with the smoke-chamber not only is the smoke caused to enter the smoke-pipe with greater readiness, but that a stronger draft on the chimney is produced than if the smoke-pipe entered the plate 1.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
